With an Ocean View? (0.5.8 Alpha)

This release adds one new feature: fluids placed in the background are now treated as fluid sources. So, for example, if you place some water in the background on a cell with nothing in the foreground, water will continuously flow into that foreground cell until it remains occupied. This is intended to function similar to an ocean in Starbound.

This also fixes a huge bug that was causing fluid contact conditions to crash the game.
